Senior Backend Developer Python Jobs in Vancouver, BC

About iCOUNTER

iCOUNTER is building the future of cybersecurity.

Modern enterprises rely on thousands of third parties, suppliers, SaaS providers, contractors, and digital partners. At the same time, attackers have shifted their focus to these trusted relationships. Today, nearly half of reported breaches involve a third party, making the extended enterprise one of the largest attack surfaces in cybersecurity.

iCOUNTER is the first Risk Intelligence company built to help organizations identify, determine, and counter threats across their ecosystem. Our AI-native platform makes a Risk Determination at the point of intelligence collection, helping organizations understand what is real, what is relevant, and what requires action.

At the center of our platform is CTOS, the Counter Threat Operating System. CTOS continuously monitors adversary activity, credential exposure, targeting behavior, and ecosystem risk across third and fourth parties. It then routes intelligence into action through automated workflows and managed operations.

If you want to help define the next era of cybersecurity and build technology that helps organizations stop monitoring threats and start countering them, we'dlove to meet you.
